To'aZZ' whom it may concern:

Be it known that l, Amuse Mob. GRAY, a citizen of the ilnited States, residing at hie. 4245 South iilroad street, Elizabeth, county of Union, State of New Jersey, have invented certain'new and useful Improvements in Apparatus for Molding Wax and other Materiale, of which, the following is a specification.

While the invention herein set forth is capable of use inihe molding oi; many materials which are reduced to a timid condition by heat and run into molds, Where they set or are chilled to the condition of a solid, it is designed more particularly for molding paraffinwax into cakes for handling and shipping.

The invention comprises the use of molds or receptacles set up in a series in alternation with hollow plates, which may form the side walls of the mold and in which the cooling medium is contained or circulated for the purpose of chilling the contents of the mold.

in carrying out the inventionl may utilize the frame, abutments, and ram of an ordlnaryfilter-press, the molds being constructed so as to be mounted upon the ordinary side rails of such a press in the same manner as are the ordinary filter-plates, and the chilling-plates may be similarly constructed to be mounted in the so one way in alternation with the molds.

in the accompanying drawings, Figure l is a plan view; Fig. 2, a side elevation; Fig. 3, a cross-section on the line 3 3 of Fig. 2; Fig. 4, a detached view of one of the molds; Fig. 5, a detached view of one of the hollow chilling-plates with its side broken away.

be the ordinary hydraulic cylinder;

B, its ram; 0, the abutment, and D D the side rails or portions of an ordinary filter-plate.

The molds E may consist merely of castings having vertical sides 6 0, connected at the bottom by a horizontal bottom piece e, thus forming a rectangular cavity for the reception. of the Wax or other material to be molded. Preferably l divide this space equally by a center piece c which divides it into two molding'cavitics of equal capacity. On the outer side of each vertical portion 6 are formed ordinary ears or lugs c", which rest upon the side rails D D of the press. he chillingplate F may consist of an open rectangular cast-iron frame f, formed at the ends with lugs f and having its sides closed by sheet-iron covers f riveted on. A cooling medium, as Water or refrigerated brine,n1ay be introduced at the pi pef and discharged at By preference arms f 5 project from the top and bottombars of. the plate to direct the cooling medium in a sinuous path.

The chilling plates F and molds E are slung upon the side bars of the press in alternation, as indicated in Figs. 1 and 2, and the assemblage of molds and plates set up closely by a hydraulic cylinder. The several inlet-pipes f of the chilling-plates may be connected by flexible tubes, asrubber hose, f, with a common supply-pipe f while the several outletpipesf may discharge into a trough G or otherwise, as may be desired.

The melted wax may be delivered into the molds in any desired or suitable manner; but preferably I prefer to arrange above the press a common pipe H, to which is connected over each compartment of each mold a'faucet I. When the molds have been filled, the wax or other material therein is quickly chilled and soon solidifies. The ram of the press is then run back, the molds and plates separated by sliding them upon the side bars, and the cakes of wax or other material removed from the molds. in the case of paraliin-Wax and most other materials that may be molded into cakes, as described, the surface exposed to the atmosphere is somewhat roughand, owing to shrinkage, is depressed or concave. These uneven ends of the cakes may he sawed off, so as to leave the cakes of uniform size. The molds are entirely open at the sides to permit of the ready removal of the cakes.

All the chilling-plates (except those at the ends of the assemblage of molds and plates) may be constructed as in Fig. 5-that is 'to say, at their ends they are ol the same height as the end bars e c of the molds and between their ends are of less height. The end plates are throughout their length of the same height as the molds, as seen in Fig. 3, where F indicatos the left-hand end plate. There is therefore an edge or guard around the assemblage of molds and plates extending above the central parts of the plates, as indicated by the dottedline a: in Fig. 2, which permits of liquid wax overflowing one mold running into another or which renders unnecessary that the liquid should he run directly into.

. the molds and not strike npon'the depressed upper edges of the plates. I am not therefore obliged to use a separate pipe or cock, as I, for filling each mold, but may deliverthe liquid to the molds in any manner or from 7 one or more cocks, which should desirably be plates, it will e ot suchoapacity as to quickly fill all the molds. If there is-a shallow layer of the liquid above the depressed topedges of the ntirely or largely sink or recede because of contraction of the wax in cool- .ing. ,nOteoursesthjeend. plates and .some ct,

top; but they are not necessarily so, as the cake may be and in practice is removed latorally. The top opening of the molds need only, therefore, be of such character as to properly admit the material. I prefer that they shall be rectangular, as they pack readily and economically in rectangular packages and may bereadily handled and shipped. It is obvious that the mere mechanical details of construction of the molds and chilled plates may be varied without departing from my invention and also that the parts of afilterpress described are not essentials, since the plates and molds may be assembled andset up against each other in other ways.

I claim .as iuvention- 1. A flat open -sided, mold permanently closed at its bottom and ends and having an opening at the top for the introduction of the material, in combination with independent removable hollow chilling-plates forming the closing sides thereof, a support upon which the mold and plates are. mounted and upon which they are independently movable laterally' or fiatwise, and means for circulating a cooling medium through the plates, whereby the mold and plates may be pressed together thus closing the mold at its sides and separated after the material in the mold is chilled or solidified to permit the removal of the cake laterally from the mold.
